Abstract (en)

A drum shell is constituted of at least one laminate wood in which at least one fiber-reinforced layer (e.g. a carbon fabric) is inserted between two wooden materials via the adhesive and which is rolled up in a cylindrical shape. By setting the mass per unit area of the fiber-reinforced layer ranging from 5 g/m 2 to 75 g/m 2 , it is possible to prevent the detachment of fibers inside the fiber-reinforced layer while controlling the shearing loss with respect to the laminate wood. The drum shell is equipped with at least one drumhead so as to produce a drum with a high sound quality and with a fine-grained exterior appearance.
